SPECIFICATION forming part of Letters Patent No. 308,240, dated November18| 1884.

(No model.)

To all whom it may concern.-

Be it known that I, A. C. CLARK, a citizen of the United States,residing at Manchester, in the county of Delaware and State of Iowa,have invented certain new and useful Improvements in Churns, and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention, and is aperspective view. the same. Figs. 3 and 4 are detail sectional viewsshowing the clamp-hinges; and Fig. 5 is asectional view of theventilator, taken on the lines x x2 of Fig. 2.

This invention has relation to rotary churns; and it consists in theconstruction and novel arrangement of devices, as will be hereinafterfully described, and particularly pointed out in the claims appended.

Referring by letter to the accompanying drawings, a designates arectangular box or churn-body, provided at its ends with the journals I)and b', which have their bearings in the tops of the uprights c c of theframed. The journal b has an aperture, e, extending longitudinallyrthrough it, for a purpose hereinafter explained.

f designates the body of the box a, and g the cover hinged thereto, asshown. The lower edges of the cover g are provided with a packing, 71.,of leather, which, when the cover is l closed down, rests upon the upperedges of the give the parts additional strength, and serve` asbearing-plates for the points of the thumbscrews Z Z', employed in theangles of the clamphinges m m and the hinged clamps a a. The

lower leaves, o o, of the clamp-hinges m m arel Fig. 2 is a verticalsectional View of secured to the rear wall of the body portion f, whilethe upper arms or leaves, p p, work in guides q q, secured to the rearwall of the cover g. as shown, thereby permitting the cover g to have aslight vertical movement up or down, in order to tighten and loosen,when necessary, the pressure on the packing h when the cover is closed.The lower portions of the hinged clamps a a are secured to the frontwall of the body f, and ltheir arms r nare adapted to be turned up, sothat the thumbscrews Z in their angular ends are carried over the top ofthe cover in line with the metal straps t', and may be screwed down toassist in compressing the packing, and also to lock the cover firmly inplace. rIhe bodyf is provided at one end with a socket, s for thereception of a pin, s', which is passed through a perforation, s2, inthe upright of the' frame into said socketto hold the churn-body in ahorizontal position and prevent it from turning, when desired, andespecially when the cover is in use as abutter-bowl. tdesignates a tubeor outlet, through which the buttermilk and cleansing water may be drawnat the proper time. In an opening in the end of the body f, and in linewith the opening c in the journal b', is rigidly set a tube, u, intowhich a second tube, a, telescopes water-tight. this tube a theventilator o, which is provided with an elongated socket, c, in itsinterior in liiie'with the opening e in the journal b', is secured, andis prevented from turning with the churn by a key-rod, w, the inner endof which isrectangular to fit the socket o, and its outer end is bentdown at a right angle to the stem, and rests in a vertical perforation,x, in a block, x', on the upright of the frame immediately below thejournal b. z is the ventilator-cap.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isy l. In a rotary churn, thecombination,with the body f and the cover g, carrying the packing h, ofthe clamp-hinges, carrying thumbscrews in their angular ends, the upperportions of said clamp-hinges working in guides secured to the rear wallof the cover, and the hinged clamps secured to the front wall of the IOObody f, carrying thumb-screws in their angular ends, and 'adapted to beturned over upon the top of the cover and secured by the thumbscrews,substantially as specified.

2. In a rotary churn, the combination, with the journal b', having thelongitudinal aperture e, with the fixed tube u, the telescoped tube u,the ventilator v, having an elongated socket, fu', the key-rod w,fitting the socket in 5 Io the ventilator, and its outer bent end engag-I ing the perforforation x in the block w', secured to the frame belowthe journal b', Substantially as specified.

In testimony whereof I aix my signature in presence of 'two witnesses.
